COMP Cams Ford Small Block Camshaft FS XE276 HR10

The COMP Cams Xtreme Energy camshaft delivers enhanced street performance for Ford Small Block engines, offering strong midrange torque and horsepower gains with a smooth yet noticeable idle and responsive throttle—ideal for mild performance upgrades. Designed for street machines, it performs best with proven combinations including the Edelbrock RPM Air-Gap intake manifold, headers, and a TCI Breakaway torque converter (2200–2400 stall) paired with a 3.73 gear ratio, producing a slightly rough idle and improved overall drivability. Featuring full-size base circles, this camshaft works seamlessly with COMP Cams Evolution hydraulic roller tappets and eliminates the need for dog bones and lifter retainers—components never intended for pre-1985 applications. This camshaft supersedes part number 31-442-8, delivering a dependable upgrade with balanced street and performance capability.
